ESP8266 Environment Widget – Software
April 30, 2016
Last post I mentioned how I got an ESP8266 board. Well, I’ve put together that with a DHT11 and MQTT to create a widget that senses temperature and humidity, then posts that on a regular basis to your MQTT message broker. The data comes out in JSON format for ease of use. I’ll cover the hardware later, once I get the rest of my prototype boards.
